Further, it can be easily manufactured, and the manufacturing cost can be reduced.

Next, an example of a construction method to which the pillar fixing metal fitting having the above structure is preferably applied is shown in FIGS. 11 and 12.
It will be described based on. In the following construction methods, a core consisting of a rigid frame structure is formed, and horizontal forces are supported by the core.Therefore, unlike a conventional building that disperses external force with a large number of columns, etc. It is characterized in that sufficient strength against external force can be obtained by using a small number of columns of material. That is, in this building method, first, the core 80 having a rigid frame structure is formed near the center of the building so as to support the horizontal force acting on the building. In this core 80, as shown in FIG. 11, four columns 82 made of four heavy steel frames are erected on a foundation, and the four columns 82 are connected to each other by a beam steel material 84 made of heavy steel frames. Build. The core is not limited to a heavy steel frame, but may be another structure as long as it can support horizontal force, such as reinforced concrete. The foundation is provided so that one support column corresponds to one foundation (independent foundation). It should be noted that FIG. 11 shows a state in which the independent foundation is buried by concrete cast in the upper part. Anchor bolts planted in the independent foundation are used to fix the columns 82 to the independent foundation. Beam steel 8
4 is provided at a height that forms the floor (or ceiling) of each floor, and the beams for one floor (so-called underground beam reinforcement) are buried by concrete poured later. In this way, the rectangular core 80 having a steel frame structure is formed. The core 80 of the steel frame can be assembled by a unloader such as a unic vehicle (a crane is mounted behind a truck).

Next, building materials are assembled by using a crane device or the like to lift up building materials such as foundation members, pillars, beams, and exterior materials. As a specific example, first, a precast concrete foundation (hereinafter referred to as a PC foundation, not shown) molded in a factory between the independent foundations 86 is lifted by a crane mechanism and disposed at a predetermined position. This PC foundation is provided with an independent foundation 86, a drain groove integrally extended from the outer surface of the independent foundation 86, and a connecting portion for connecting a plurality of block bodies to each other in the extending direction of the drain groove. There is.
For this reason, if concrete is thrown away at an appropriate thickness at the foundation laying site, PC foundations are arranged on top of it with a thin uncured mortar layer, and the connection parts are connected by bolts, etc., at the same time as the foundation is formed. The advantage is that a drain can be constructed. The crane device may be one mounted on a mobile crane, or a main body shaft extending above the core 80 may be rotatably erected while being supported by the core 80, and a boom may be rotated above the main body shaft. It is possible to use a crane mechanism that is pivotally attached to the boom, and has a boom mechanism provided with a lifting device such as a hook at the tip of the boom.

Then, using a crane device, as shown in FIG. 12, a column 30 made of laminated wood is erected on the foundation. At this time, the pillar fixing fitting of the present invention is used. The use of the pillar fixing fitting of the present invention is particularly effective when a large pillar made of laminated wood is used as in the present construction method. Further, the pillars 30 and the core 80 and the pillars 30 are connected by beams made of laminated wood. To connect the core 80 and the beam, a connecting plate is preliminarily provided by welding at a connecting position of the column 82 or the beam steel material 84 with the beam, and a split groove provided at the mouth of the beam is fitted into this. And fix with bolts. The beam 90 and the pillar 30 are connected to each other by using a beam fixing metal fitting so that the through holes of both of the cross-joint portions of the beam 90 and the pillar 30 are penetrated through, and a bolt is fitted into the hole where the position is matched. It is done by passing it through and tightening the nut.

When the skeleton of the building is formed in this way, the frame is fixed with a brace bar with a turnbuckle. However, when the floor is made of a rigid heat insulating panel, the rigidity is ensured by the panel, and thus it is not always necessary. Furthermore, using a crane device, floors, walls, and roofs will be constructed with heat insulating panels and the like.
If necessary, appropriate makeup work is applied to the wall surface and floor surface, and a waterproof roofing material is attached to the roof base surface, and other necessary interior work is applied.

Since the building constructed by the above-described construction method supports the horizontal force acting on the building by the core 80, it is not necessary to dispose the studs, and the number of columns to be used is greatly reduced. be able to. Also, the structure of the ceiling is core 8
Since it can be supported by 0, the structural material such as Tsuka can be simplified. And when building a normal house by this construction method, it is about 4 by installing steel frames, columns, beams and high heat insulation panels.
It only takes a few days, and the construction period can be greatly shortened. In this way, the construction material cost can be reduced and the construction efficiency can be significantly reduced, so that the construction cost can be significantly reduced. Also, since there are no studs, it is possible to secure a wide open space, which was impossible with wooden construction. Therefore, the layout can be changed easily by changing the partition, and it is possible to cope with changes in lifestyle. Furthermore, since the number of pillars is small, the entire building can be made lighter, so it has high earthquake resistance.
In addition, by using wood such as laminated wood for the beams and columns like the above-mentioned building and using a high heat insulation panel for the exterior material, it is possible to include a core made of steel frame with high heat conductivity, The property can be extremely improved. Further, by using a highly heat-insulating panel, it is possible to prevent the occurrence of dew condensation, prevent the generation of mold and mites, and have excellent sound insulation and airtightness. As described above, the above construction method has many advantages.

In the above embodiments, the case where the pillar made of laminated wood is erected has been described, but the pillar fixing metal fitting of the present invention is not limited to this, and when the pillar made of various materials and forms is erected. Of course, it can be used for. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
